Letters Patent N 96,470, dated liormnber 2, 1869.-

The Schedule `referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, E. D. N0n.10.\*,'ot` Cuba, in the county ot' Allegany, und in the Stute ot' New York, have invented n. new :md usei'ul Improvement in Dooror Gute-Springs; :md I do herebydeclure thatthc following is nihil, cleor, and exact. description ot' the Construction und olwrution-of the snme, reference beingl lmd'to the :umexed drawings, making a port, ot' this speeifieotiou, in which- Figure 1 is :L front elevation of door or gute with my improved spring,r nttnched.

Figure. 2 is n. top view of sprinff.

Figure 3 is :L front View of' some.

My invention consists of un improvement in the methods iormerly employed for closing.;r doors or gutes, by menus oil springs; and Its object is to obtnin n more servieenblo und reliuhle spring thun the ones hithertoin use for thnt. purpose, so thntthc spring (-:m be easily detached, or :ldjusted, or reversed, so that it will hold the. door, either open or shut, according to the way in which the spring is placed.

To enable others skilled in the :u't to make und use my invention, I will proceed to describe its construction und operation.

A represents door or gute.

B, the fraune. v

G represents :i steel, oeil-on, or hmss pin, seeured firmly to door-trame by menus of screws or bolts, the 11h sitting out lrom thtv frume n suliieient distnuce to' allow the spring to he taken oli' or put on ot euse.

D represents n double or single spiral spring, mode to lit' loosely over the pin C.

F represents n spring, attached tirinly to door or gite, by means oiserews or bolts, allowing sil-id spring to set out townrd thc upper end, which is attached to und ot' the spring,r I) h r menus of u. link, mzu'ked E.

The operuiion is' as follows:

\Vhen the door or gute. is opened, thc spring.;r I) is drown out h r the eonneeting-link E, und. when nllowed to elose, is drown to hy tho notion otthe double. or single spiral spring, eonueeted with the spring.r F by connecting-link E. The combination of thc spring 1), :md spring l`,:u1d connecting-link E keeps t-hc door or gute tightly closed, by reason ot' the outward tendeney of the spring;r marked F. Remove the spring,

:md plnec'it upon its'stmnlu-rd with the bock coil upon the inside, :md the spring will now hohl thc door open', instend of shut. v i A I nm aurore' that spiral springs ure used for closing doors :md gates.

I do not claim :is'new t-he spiral spring for closing doors or gates; but

I do elnim :is new, :md desire to secure by Lett-ers Pntente- I 'lhc removable :md reversible spring D, formed of eoileil wire, plneed upon the stnndnrd U, :nnl connected to the spring F by the link l), ull :is und for the purpose set forth.

In testimony that I claim the foregoing, I have, hereunto set my hund, this` 29th dztyot' July, 1869.
